APPARATUS FOR LIFTING FLUIDS.

Specification of Letters Patent.

Patented Jan. 20,1914.

Application filed November 27, 1912. Serial N 0. 733,882.

To all whom it may concern.-

Be it known that I, PATRICK J. ONEILL, a citizen of the United States, residing at Bakersfield, in the county of Kern, State of California, have invented certain new and useful Improvements in Apparatus for Lifting Fluids; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for lifting fluids from wells.

The object of the invention resides in the provision of an apparatus of the type named which is adapted to be lowered in wells of great depth and operated when disposed beneath the fluid level of the well to lift the fluid through the medium of compressed. air and discharge same by means of a suitable pipe line exteriorly of the well.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which- Figure 1 is a plan view of the apparatus. Fig. 2 a section on the line 2-2 with the parts of the apparatus in the position they would occupy before the operation of lifting the fluid is instituted. Fig. 3 a View similar to Fig. 2 with the parts in the position they would occupy after the operation of lifting the fluid is instituted, and Fig. 4 a section on the line H of Fig. 2.

Referring to the drawings the apparatus is shown as comprising a casing A of fluid tight structure and including parallel side walls 10 and 11, a top Wall 12 and converging side walls 13 and 14:, the former being in the form of a removable gate slidably mounted in suitable grooves 15 formed in the inner side of the side walls 10 and 11 and seating in a groove 16 formed in the lower end of the side wall 14, the removable mounting of the wall 13 being such that when same is in a completely closed position the casing A will be liquid tight. Extending longitudinally of the wall 13 and opening through the upper end thereof is a passage 17. The lower end of this passage terminates in an inwardly directed air discharge nozzle 18 spaced from the bottom of said wall and inclined upwardly toward the top 12. Communicating with the passage 17 at the upper end of the latter and suitably secured to the wall 13 is an air pipe line 19 which extends upwardly and is of a length suitable to the depth of the well in which the device is to be operated. Secured to the top wall 12 is a pipe line 20 which is alsoof a length suitable for the depth of the well. The air pipe line is of course connected with a suitable air compressor disposed without the well and also with a suitable means for effecting the lifting of the wall 13 of the casing A so as to open communication be tween the interior of the well and the interior of the casing A.

In the use of the apparatus the casing A is lowered into the well so as to be immersed in the liquid at the bottom of the well. The wall or gate 13 is then elevated and at the same time that this wall or gate is elevated the air is turned on through the pipe line 19. The liquid will then rush into the interior of the casing A up the inner side of the wall 1 1. This liquid in its upward movement is caught by the air discharging from the nozzle 18 and thoroughly aerated and lifted upwardly through the pipe line 20 and discharged exteriorly of the well in which the device is operated. This method of raising fluid eliminates the resistance due to inertia, while the aeration of the fluid causes same to rush toward the upper end of the pipe line 20 impelled by its own pressure owing to its head and velocity and force of air.

That I claim is 1- 1. I11 an apparatus of the class described, a casing having a movable side wall provided with a passage the upper end of which opens through the upper end of said movable side wall while the lower end terminates in an inwardly directed air discharge nozzle inclined toward the top of the casing, means for securing an air pipe line to the movable wall in communication with said passage,

and means for connecting a pipe line to the top of the casing in communication wlth the interlor of the latter.

2 In an apparatus of the cliss describ (1, I Ii -testimony Wlier'eofiI aflixmy signature, a casing having a" discharge outlet and a 'in the' p'rer'serfee of two Witnesses;
